Design of Left-Handed Material Microstrip Antenna

With massive MIMO technology placing higher demands on the directionality of antennas, antenna systems loaded with metamaterial lenses have become the focus of research. The millimeter wave antenna has the characteristics of small size, light weight, easy integration, and has been widely used in the military. Loading the left-hand material lens with negative refractive index on the millimeter wave antenna not only effectively converges the antenna pattern, but also achieves the purpose of improving the antenna gain.
